SbModbusArrayAttribute

具有源代码生成器，可为 struct 生成部分方法。

使用方法

声明 partial struct，并且需要带有 SbModbusArrayAttribute。

示例

using System.Runtime.InteropServices;
using SbModbus.Attributes;
using SbModbus.Models;

namespace ModbusTest;

[SbModbusArray(typeof(ushort), 4, BigAndSmallEndianEncodingMode.DCBA)]
public partial struct UShortArray4
{
}

会自动生成

using System.Runtime.InteropServices;
using static SbModbus.Utils.Utils;
namespace ModbusTest
